We all know that some things are right. For example, it is right to be 1 to other people. It is also right to look after the environment. Some things are 2 wrong, too. For example, we should not hurt or bully(欺负) others, nor should we litter. Rules often tell us what is right or wrong.
Rules can help the public make the right 3, and remain safe. Car drivers have to follow traffic rules that tell them the right things to do on the road to avoid accidents. Cyclists who give signals before turning or stopping help prevent 4, too.
If people follow rules without taking other matters into consideration, it will be 5 for them to form what is sometimes called a "black and white" view. For example, they may believe that people should always tell the truth, and that lying is 6 acceptable. Such people always stick to their views, even if it means that they may get into 7.
Sometimes it may not be so easy to know 8 what is right or wrong. Some people choose not to eat meat because they believe that it is 9 to eat animals, but others argue that they can eat meat and 10 be kind to animals; some say that stealing is always wrong, but others think that one does not need to feel so 11 when stealing some food to eat, if he lives in a really 12 area and he is starving.
Rules help us live together in harmony(和谐), because they show us the right way to 13 others. However, some people argue that rules may be 14, having known that rules change all the time, and that some schools have some rules and others have different ones—so who is to 15 what is right?
